Patented Aug. 18, 1953 UNTTED STATES PATENT OFFICE FOB. BINDING BOOKS Milton H. November, East Orange, N. J assignor to Spiral Binding Company, Inc., New York, N. Y., a corporation of New York" Application July 2, 1948, Serial No. 36,693

27 Claims. (01.140-92-7) This invention relates to machines for makin books of the type in which a plurality of sheets are loosely bound together by means of a helically shaped binder.

Patent No. 2,300,544 issued to A. Freundlich, November 3, 1942, discloses a binding machine which accepts a book provided with a plurality of holes arranged in a row along the binding edge thereof for the reception of a. helical wire binder and which is designed to shape the book so as to align the holes thereof into a substantially helical path by means of ahand operated carriage bearing a series of comb-like helicallyshaped prongs, to clamp the book in its shaped condition during the binding operation, to form a wire into a helical shape andautomaticallyfeed it into the helically arranged holes of the book, to trim the portion of helical coil threaded through such holes to book size and tobend,the ends of the trimmed helical coil .soasto lock such coil in position on the book. While the machine of this patent was a long stepforward in this art, and was highly desirable an Qfieotive for the purposes for whichit was designed it was not wholly automatic, and was mechanically complex and bulky.

It is the principal purpose of this invention. to provide a machine of the indicated type which is wholly automatic in performing its sequence of operations, which reduces the need forv manual labor to a minimum and which at the same time, is capable of a higher rate of productivity than prior known machines of this type.

Another object of theinvention isto provide a helical bindin machine which is relatively simple and compact in construction and which is relatively inexpensive to construct and operate.

A further object of the invention isto provide an improved machine of the indicated type, which is relatively simple to operate, has alow main- ;tenance cost and produces a better product more ,expeditiously and economically 7 than prior rnaichines of this type.

Other objects and advantages of the invention :will be in part obvious and in partpointed out in the following detailed description of the machine, 'which should be read in connection with the accompanying drawings, in which Fig. l is a front elevational view of theniachine of this invention with the top facing panel relooking toward the left thereof, as 1 of the drawings;

Fig. giis a top plan view of the machine;

Fig. 5 is a sectional view taken along the line 5 5 of Fig. 4;

Fig. 6 is a top plan view of the machine with the top frame casting and work table removed to show themechanism within the upper housing more clearly;

Fig. '7 isan enlarged, detailed, side elevational view, partly in section, of the upper portion of the machine, with certain parts eliminated, to show moreclearly the arrangement'of the book clamp, wire guide bar, book aligning prongs, pliers andactuating means therefor; the book clamp and book aligning prongs being shown in retractedposition and the pliers being shown me. raised position ready for acceptance of an unbound book;

Fig. 8 is. a similar view showing the pliers in lowered position, the book clamped .to the table and the alignin prongs in fully advanced posiviewed in Fig.

tion Within the book and ready to be retracted;

Fig. 9 is a similar View showing the aligning prongs removedfrom the clamped book and the wire guide in position on the coil being inserted, the pliers still bein in loweredposition;

Fig. 10 is a view similar to Fig. 8 and showing in an enlarged schematic form the relation of the pliers and aligning prongs, wire guide and clamp just prior to, thejremoval of the aligning prongs from the book;

Fig. 11 is a vertical sectional view taken along the line, i I -H of Fig. 4 through the top frame casting of the machine and showing the table adjusting means for books of varying thicknesses;

Fig. i2 is atop plan View of the graduated scale and the table adjusting screw; such scale being calibrated in book. thickness values;

Fig. 12a is a detailed front elevational view, partly in section, of. the scale and the upper, end of. the table. adjusting screw;

Fig. 13 is a schematic view showing the arrangement for driving the wire into the coiling die and the ,rneans for lubricating such die during the wire .forming operation;

Fig. 14 is anenlarged vertical sectionalview taken through the wire forming die jsh wn in Fig. 13," I

Fig. 15 is, ahorizontal sectionalview of the wire feedmechanism, such view being takenjalong the line, |5 ,|.5 ofFig. 13; f

Fig. 16 is a vertical sectional view on a reduced scale of the wire feed, mechanism shown in Fig. 15, such view being taken along the line' se ne
